The Do’s and Don’ts of Thawing Frozen Pipes SafelyIt’s 6 a.m. on a January morning. The house is quiet, you are going to brew some coffee and then nothing. No water. You check the sink, the shower, the laundry tub. Still nothing. That sinking feeling sets in as you realize Minnesota’s deep freeze may have turned your pipes into ice plugs. What you do next can be the difference between a simple fix and thousands of dollars in water damage.

Why Frozen Pipes Are So Dangerous

Frozen pipes don’t just stop water flow, they expand as ice forms, putting pressure on the pipe walls. When the ice finally melts, weakened pipes can burst, flooding walls, basements, and cabinets. Acting quickly, and correctly, is critical.

The Do’s of Thawing Frozen Pipes

Do these steps to reduce damage and restore water safely:

  • Do shut off the main water supply before you begin, just in case a pipe has cracked.
  • Do open the affected faucet to relieve pressure and allow melting ice to escape.
  • Do apply gentle heat using a hair dryer, heating pad, or warm (not hot) towels.
  • Do start thawing near the faucet and work your way toward the frozen section.
  • Do keep heat moving—slow, even warmth is safest.

The Don’ts of Thawing Frozen Pipes

Avoid these common mistakes that cause bursts and fires:

  • Don’t use open flames like torches, grills, or space heaters.
  • Don’t pour boiling water directly on pipes, especially PVC—this can cause cracking.
  • Don’t ignore hidden pipes in walls or ceilings; thawing blind can be risky.
  • Don’t wait too long, the longer a pipe stays frozen, the higher the risk of failure.
